An improperly positioned load can overload the liftgate and result in sudden liftgate failure and/
or increased risks to personnel of being hit or crushed by loads. IMPROPERLY POSITIONED
LOADS MAY RESULT IN SERIOUS PERSONAL INJURY AND/OR DEATH. Always position
loads properly on the liftgate platform. Follow information below on how to position loads
properly.
POSITION LOADS PROPERLY ON PLATFORM
 NEVERo-center theloadon theplatform, from sideto sideoraway from truckas this
may overload the liftgate. The center of weight of the load should NEVER be placed beyond
the center of the platform load surface, away from truck. Loads should be placed close to the
platform edge nearest truck. If a load is not uniformly distributed, then the heaviest portion
should be closest to the edge of the platform nearest the truck. NEVER allow any part of the
loadtoextendbeyondtheedgesoftheplatform’satloadsurface.NEVERallowanypartof
the load to extend over or on, the tapered ramp portion of the platform unless the platform is
lowered completely to the ground and the ramp is supported by the ground.
!WARNING
DO NOT OVERHEAT THE HYDRAULIC PUMP
Exceeding the duty cycle of the hydraulic pump, can overheat many components,
including the gear pump, the hydraulic motor, the motor start solenoid, valve coils, etc., and
signicantlyshortentheexpectedlifeofthesecomponents.Inextremecases,immediate
damage to the pump or related components may occur. Refer to the Thermal data below.
THERMAL DATA: To avoid overheating the motor do not operate this unit for more than 5
cycles/ 10 minutes with the maximum load. The motor then must be allowed to completely
cool down to ambient temperature before cycling the lift again. This unit also has a 10% duty
cycle, which means the liftgate can be cycled no more than 2 cycles/10 minutes constantly
with the maximum load.

Chain Anchor Links SAE 10 to SAE 20 oil 100 cycles
Locking Cams SAE 10 to SAE 20 oil 100 cycles
*NOTE: TVLR gates which see less than 50 cycles per week must be lubricated in the areas
listed above no less than once a week. Once lubricated, run the gate up and down
through one complete cycle to spread lubricant more evenly.
14.Torsionbaradjustment(Seegure3).
A. Place platform in stowed (vertical)
position.
B. Remove 5/8” diameter bolt (A) from
center of tension adjusting bracket.
C. Place ½” square breaker bar in the
square hole of the adjusting bracket
pin.
D. Turn breaker bar counterclockwise to
relieve tension on 3/8” diameter bolt (B)
and remove it from the bracket.
E. To increase tension, rotate bracket
counterclockwise until desired tension
is reached. Line up hole in bracket
to hole in slider platform support and
replace bolt (B).
13. Check the pump relief pressure and also the motor amperage at this pressure. These
values should be as follows:
Model Max Amp Draw Relief Pressure (psi)
